A live view · for householders and place

Your home is not the average home

Almost everything you are told about your home's energy arrives as a single number: a band, a running cost, a saving. Here is the city that number was drawn from. Every Nottingham home our stock model can price from public records, 107,336 of them, simulated through a full year, hour by hour, sorted by how long the heating is modelled to run. Move the marker and the curve answers: where a home like that sits, and how far the average is from most of them. Nothing here runs on your device; every figure is a verified, published record.

The story of these numbers: Your home is not the average home.

One number, or a distribution

Every home in the city, by the hours its heating is modelled to run. Move the marker to read where any home on the curve sits.

A home that heats for 3,592 hours a year sits in the lower cluster of homes. About 49% of the city's homes heat less, and it is about the median.

Or read a Nottingham ward's typical home:

Bar area is proportional to homes; wider bars are small groups merged to keep every group at ten homes or more. One home in ten heats for fewer than 2,474 hours, one in ten for more than 5,175.

The curve has two humps and a thin middle, and the median sits on the shoulder of the lower one, with a second, larger cluster of homes above it. An average drawn across all of this lands where comparatively few homes actually are. The further a home sits from that middle, the less the average has to say about its bill.

What this view shows, and what it does not

  1. It shows the spread of the method's modelled heating hours across a real cohort, never a measurement of any particular home's meter.
  2. It shows aggregates only. The smallest band is ten homes; no address, identifier or figure for a single home is published.
  3. The marker is a reading tool for the curve, not a reading of your home. A reading of your own can be built from what is already recorded about your house, in the governed record, before anyone visits.

Ask this about your place

Nottingham is one city, compiled from records that are already public. The same cohort can be built for any city, borough or patch in England, and the same curve drawn for it. Name yours and we will return the first cut: the homes, the spread, and where the outliers sit.

Needs your name, email, organisation and a patch.

We send exactly what you enter here: name, email, organisation, patch. It is used only to compile the first cut and reply (usually within a few days). Indicative figures from public records; no data is needed from you to start.
